Multigrid preconditioners for the hybridized Discontinuous Galerkin discretisation of the shallow water equations
Jack D. Betteridge, Thomas H. Gibson, Ivan G. Graham +1
Numerical climate- and weather-prediction requires the fast solution of the equations of fluid dynamics. Discontinuous Galerkin (DG) discretisations have several advantageous prope…
